i am putting in a super-simple gigabit network in my studio so i can access my soon to be built network storage box over a 1000mbit instead of 100mbit LAN. i am bad at networking (figuring out the configuration on the NAS is gonna be a blast i am sure) but is my understanding correct (see image)? will the switch (a 4-port netgear GS605) be specific in where i plug the cable from the router? also, my understanding is that the router (a linksys WRT54G) has a firewall to keep the NAS from being open to the internet (i know nothing is perfect, but is it adequate?) i have the wifi as i sometimes like to get away from the desk; i understand that i will be limited in speeds to the NAS when i do this, but this way i can get the gigabit speed when i am wired up (i hope?). anything else i should know? i do think i need to get a couple of CAT 5e or CAT 6 cables to get the full speed - i am not sure what my current cables are.
